How to get excel to display a certain number of significant figures?

Question

I am using excel and i want to display a value to a certain number of significant figures.

I tried using the following equation

=ROUND(value,sigfigs-         


        

Answer 1

You could try

=ROUND(value,sigfigs-(1+INT(LOG10(ABS(value)))))

value :: The number you wish to round.

sigfigs :: The number of significant figures you want to round to.
